Scientists at the University of California, Los Angeles present research on a curious cosmic phenomenon known as “whistlers” -- very low frequency packets of radio waves that race along magnetic field lines. Appearing in the Physics of Plasmas, the study provides new insights into the nature of whistlers and space plasmas and could one day aid in the development of practical plasma technologies with magnetic fields, including spacecraft thrusters that use charged particles as fuel.

Researchers comparing several clonal strains of isoniazid-sensitive and resistant tuberculosis bacteria found shared changes to mycobacterial metabolism that bolster the evidence for a new proposed drug target.

Igloo was developed by the Department of Homeland Security (DHS) Science and Technology Directorate (S&T), and is currently in use by select units of U.S. Immigration and Customs Enforcement (ICE) Homeland Security Investigations (HSI), the lead agency for investigating human smuggling.

According to suicide prevention experts, asking a child directly about suicidal thoughts is usually the best thing a parent can do to help their child open up about their emotions. Even if their child is not struggling with suicide or depression, parents can model for their child that it is good to talk about serious emotional concerns with trusted adults and important to reach out to friends to have these conversations, too.

In the first comprehensive study of the forefoot joints of ancient hominins, to be published online in PNAS, an international team of researchers conclude that adaptations for bipedal walking in primates occurred as early as 4.4 million years ago

A new study led by the University of Washington uses data gathered by floating drones in the Southern Ocean over past winters to learn how much carbon dioxide is transferred by the surrounding seas. Results show that in winter the open water nearest the sea ice surrounding Antarctica releases significantly more carbon dioxide than previously believed.
